Pak J Radiol Jan ;25(4):175-8.

Gastrointestinal stromal tumors (GIST) are the most common mesenchymal neoplasms of the gastrointestinal tract however these account for <1% of gastrointestinal tumors. Most common site is the stomach (50?60%), followed by small intestine (30?40%), colon (7%) and esophagus (1%), they rarely have extra-gastrointestinal involvement.1 GIST of the anal canal are extremely rare. They along with GIST of the rectum represent 5% of GIST.2 Of the anorectal GIST, GIST arising from the anal canal account for only 2%?8%. We present a case of recurrent anal GIST which was earlier treated by local excision.
